- His family was very poor but his intelligence earned him a scholarship to the University of Tubingen to study for the Lutheran ministry.

- Johannes Kepler unfortunately died on November 15th, 1630 at the age of 58 years old.

All about Astronomy

- Johannes Kepler was known for Kepler's 3 laws of planetary motion.

- He was a big part of the 7th century astronomical.

- In 1609 the astronomic nova was published.

- As an astronomy, Kepler thought that we are in a sun centered universe where all of the planets revolve around the sun.

- He invented an improved version of the refracting telescope.

-Johannes Kepler obtained his B.A degree in 1588 and his M.A degree in 1591

- He invented the Keplerian telescope

- His first law was that the orbit of each planet is an Ellipse, and the sun is at one focus.

- His second law was that the line joining the planet to the sun sweeps out equal areas in equal intervals of time.

- His third and final law was that the square of the orbital period is proportional to the cube of the semi-major axis.

The picture below is the Keplerian telescope.

The picture above is called the ellipse.
